Re: A "clunk" noise when shifting gears

Hmmm. Yesterday, I made a relatively quick reverse to forward shift (not gear grinding quick) backing out of a parking space to avoid getting hit from behind. I heard a definite clunk sound. Felt like I had run over something in the parking lot. Probably due to the momentum shift.

First instance I have heard in 2 months of ownership. I will be paying attention more closely.

My 2000 JGC did this over the 10 yrs I owned it. Almost always heard upon shifting and backing out in reverse. Assumed it was just the suspension moving.

Re: A "clunk" noise when shifting gears

I just checked mine again. Loud clunk shifting from D to N when standing still. As you shift into D you can feel the drive train load up. It takes maybe a second or so. It sounds like the rear diff or something. The interesting thing is that it does this in all the modes except SNOW!?
Anyone have any more info on this? The Jeep is going in for a service in about 2 weeks and would like them to sort it out then.

Re: A "clunk" noise when shifting gears

Quote:
When shifting to Park (or Neutral) the driveline torque is rapidly released (as the clutch passages are vented by the manual valve). This is an uncontrolled shift - there are no solenoids involved. There are no orifices to slow down the decay of pressure, because of potential safety issues; when you shift to Park or Neutral, we want the clutches vented as rapidly as possible. Unfortunately there is some windup in the driveline and suspension, so when the clutches are rapidly vented, the torque is released and the driveline "snaps back" to its untorqued position.
This is a starcase for a DR 1500 pickup with a 5.7l but most importantly for an 545RFE trans. Chrysler has done things to limit this but is still a biproduct of the design of the transmission and is normal operation.

And I am neither drunk nor high

SSSSOOOoooo your telling me you think subaru is going to be the answer to your prayers... 100k headgaskets on every car made since the 80's... NO car manufacturer is perfect, PERIOD. A honda dealer across the street from us had some people with a new odyssey with "my honda lemon" plastered all over its windows and people standing around it with signs this last week infront of the new multi million dollar honda service center.

A clunk in a transmission may not be as refined as a BMW but EVERY car bought from bmw is contributing another 30k to the engineering of that vehicle over its equivalent chrysler vehicle... You cannot be that upset you saved 30k and because of that saved money you have to deal with a normal clunk... Unless a clunk is worth 30k to you?

Re: A "clunk" noise when shifting gears

Mine does the same noise as well. I took in for service last week and mentioned it to them and the guy said it was normal. This is in Germany.

Re: A "clunk" noise when shifting gears

I have had the same problem. Along with the tranny "shudder" problem these seem to be the only large concerns I have...(although I should have gotten 20's instead of 18's on my Limited!!) I've found a quick work around.... When slowing to a stop, once you're almost stopped (and I mean ALMOST stopped) put the tranny into N then stop completely and put in reverse or park.... seems to get rid of the majority of the "clunk"ing. I know this isn't as safe or as ideal as a real fix, but until they fix it (if they do..) it seems to stop what sounds like the tranny lunching itself all the time...

Re: A "clunk" noise when shifting gears

I was experiencing this same problem. I took it in for service and TSB 21-010-12 was done. It was at the service department for 3 days...but the problem was solved :-)

Re: A "clunk" noise when shifting gears

Same here....same TSB but I am waiting for the dealer to get the part in. To all who have experienced the clunk this is the tsb to tell your dealer to check for you. Don't let them tell you this is normal, cause it's NOT!!!!!!

Even the shuddering....that is another TSB. www.wk2jeeps.com click on maintenance it will give you all the TSB's for your vehicle and what you are experiencing.
